I walked right in hip hop, like, "Where my dinner be at?"
I ate that and I was like, "Where my dinner be at?"

from Lil Wayne – Live From 504 Lyrics on Rap Genius

Meaning

Weezy has often called himself “the rapper eater,” as he metaphorically “eats” rappers that are lower than him. He just ate hip hop entirely (meaning every single rapper in the game), and not only is he still hungry, but it was so easy and inconsequential for him that he doesn’t even realize that he did it; he is still waiting for his dinner (although it could also imply that hip hop was served as an appetizer, and that he is still waiting for the main course, maybe a worthier challenger?)
